Introduction
\n<\/strong>
\nDocker is an application that simplifies the process of managing application processes in containers. Containers let you run your applications in resource-isolated processes. They\u2019re similar to virtual machines, but containers are more portable, more resource-friendly, and more dependent on the host operating system.<\/p>\n

Prerequisites
\n<\/strong>
\nTo follow this tutorial, you will need the following:
\nOne Ubuntu 22. x server is set up by following the Ubuntu 22. x initial server setup guide, including a sudo non-root user and a firewall.
\nAn account on Docker Hub if you wish to create your images and push them to Docker Hub.<\/p>\n

To install and use Docker on Ubuntu, you can follow these steps:
\n<\/strong>
\nStep 1: Update Package Lists.<\/strong>
\nMake sure your package lists are up-to-date by running:
\n#sudo apt update<\/p>\n

Step 2: Install Necessary Dependencies<\/strong>
\n#sudo apt install apt-transport-https ca-certificates curl software-properties-common<\/p>\n

Step 3: Add Docker GPG Key.<\/strong>
\nCurl -fsSL https:\/\/download.docker.com\/linux\/ubuntu\/gpg | sudo gpg –dearmor -o \/usr\/share\/keyrings\/docker-archive-keyring.gpg<\/p>\n

Step 4: Set Up Stable Docker Repository<\/strong>
\necho “deb [signed-by=\/usr\/share\/keyrings\/docker-archive-keyring.gpg] https:\/\/download.docker.com\/linux\/ubuntu $(lsb_release -cs) stable” | sudo tee \/etc\/apt\/sources.list.d\/docker.list > \/dev\/null<\/p>\n

Step 5: Install Docker Engine<\/strong>
\n#sudo apt update
\n#sudo apt install docker-ce docker-ce-cli containerd.io<\/p>\n

Step 6: Manage Docker as a Non-Root User (Optional)<\/strong>
\nIf you want to avoid using sudo each time you run Docker commands, add your user to the docker group:
\n#sudo usermod -aG docker $USER
\nAfter running this command, you will need to log out and log back in or restart your system for the changes to take effect.<\/p>\n

Step 7: Verify Installation
\n#docker \u2013version
\n#docker run hello-world
\nThe docker run hello-world command should download a test image and run a simple container, confirming that your Docker installation is working correctly.<\/p>\n

That’s it! You have successfully installed Docker on Ubuntu. You can now start using Docker to build, ship, and run containerized applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
